FWIW, that's what I see:
- using gdi (because I've forced Emacs to fail loading usp10.dll or
by using Emacs.fontBackend: gdi) => Emacs "finds" U+2200 at glyph #3
of DejaVu Sans Mono.
- using uniscribe (by means of Emacs.fontBackend: uniscribe) =>
Emacs correctly finds U+2200 at #421 of MS Mincho.
- leaving it to itself to choose (no Emacs.fontBackend): it "find"
the #x3 glyph in DejaVu Sans Mono
so it seems gdi-related.

BTW, perhaps there should be a (trivial) function to list available
backends. Currently the only way I can see is
(cdr (assq 'font-backend (frame-parameters)))
and that depends on Emacs.fontBackend not being set to limit the list.
